Unformatted text preview: Bipolar Junction Transistor Lesson 5 Bipolar Junction Transistor Objective: after learning this section, you will be able to: Draw the symbols and name the leads for npn and pnp bipolar junction transistors; Describe the principle of operation for bipolar junction transistors; Define and relate the beta and alpha parameters; Bipolar Junction Transistor Objective: after learning this section, you will be able to: Determine the currents and voltages in a dc one- transistor circuit; Locate on the transistor collector curve active region, cutoff region, saturation region , and breakdown region; Interpret ratings on a transistor data sheet. Symbol and Leads Three lead device: collector, base, emitter. Two types: npn, pnp. np n E B C B E pn p C Diode models for npn and pnp Two types: npn, pnp. Operation and testing can use diode model for interpretation L E S O N ~ 2 Principle of Operation BE junction forward- biased; BC junction reverse-biased (both...
